MACHINE FOB WAX-FINISHING- THE EDGES OF THE HEELS OF BOOTS AND SHOES.

Specification of Letters Patent.

Application filed September 5, 1914. Serial No. 860,347.

States, residing, respectively, at Lynn and- Swampscott, 1n the county of Essex and State of Massachusetts, have invented new and useful Improvements in Machines for Wax-Finishing the Edges of the Heels of Boots and Shoes, of which the following is a specification.

This invention relates to a machine forwax treating and burnishlng the edges ofthe heels of boots and shoes in which a rotary work rubbing member and a receptacle for wax are employed.

The novel features of the invention reside first in the means whereby the wax is fed from the wax receptacle to the periph-.

cry of the rotary work rubbing member and second in the construction and arrangement of parts whereby the means for feeding the wax from the wax receptacle to the periphery of the rotary work-rubbing member are thrown into operation to feed said wax, as set forth, when the operator presses the heel of the shoe against the periphery of the work rubbing member. In machines of the class hereinbefore set forth it is very desirable that sufficient wax should be fed to the periphery of the work rubbing member to perform the work and no more, and it is further desirable that the amount of wax fed to the work rubbing member during a given time should be capable of regulation that is, that it should be possible for the operator to quickly and easily adjust the machine so as to feed more or less wax during a given time to the periphery of the work rubbing member as may be desired, and it is also very desirable that when the work rubbing member is not in use to wax treat ,the edges of the heels of boots and shoes no wax should be fed to the periphery of said member. If too much wax is applied to the periphery of'the work rubbing member it results in applying too heavy a coat to the edge of the boot or shoe heeland also the wax is liable to run down the sides of the work rubbing-member and get onto the of the work rubbing member it is thrown off and is liable to be thrown in a heated condition upon the hands of the operator and on different parts of the machine tothe Patented Jan. 9, 1917.

great detriment thereof. Moreover, in mafi chines of this class the work rubbing mem ber is utilized for the wax treating operation for the edges of the heels of boots and shoes during only about one-third of the time, the operator during the rest of the time being employed'eithe'r in handling the shoe, padding with a'padding brush, or in beading .and in polishing with a polishing brush. When wax is being constantly appliedto the periphery of the work rubbing member and not being immediately used, it results in deterioration of the Wax as well as the otherdifliculties hereinbefore set forth, and it is the object of this invention to provide a machine which, under normal conditions, will not supply wax to the periphery of the work rubbing member, but as soon .as the operator presses the edge of the heel against the periphery of the work rubbing member, the wax feeding means will be immediately and automatically thrown into operation by reason of this pressure and the wax feeding means will then begin totransfer wax in its melted condition from the wax receptacle to the periphery of the work rubbing member in order that it may be applied to the edge of the heel which is to be wax treated. The mechanism is also so constructed and arranged that when the operator removes the heel from the periphery of the work rubbing member the wax feeding means will be automatically thrown out of action and the feeding of the wax stopped.

To these ends the invention consists in the improved mechanism whereby wax may of the Work rubbing member, the feeding of v the wax to said periphery will'begin and when said heel is removed from the periphcry of the work rubbing member the feeding of said wax will cease.

The invention further consists in the combination and arrangement of parts set forth in the following specification and particu larly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a rear elevation of a portion of a wax finishing machine for bootsand shoes embodying our improved mechanism for feeding the wax from the wax receptacle to the periphe ry of the work rubbingmember. Fig; 2 is a detail sectional elevation taken on line 22 of Fig. 1. Fig. 3 is a sectional eleva feeding member illustrated in Fig. 6. Fig.

Stis a sectional elevation taken on line 8'8 of Fig. 3. I

Like numerals refer to like parts throughout the several views of the drawings.

In the'drawings Figs. 1, 2,3 and 8, 10 is a rotary work rubbing'member preferably formedof felt or other soft material covered with cloth in accordance with the ordinary construction of such work rubbing members. Said work rubbing .member is fastened to a shaft 11 j ournaled to rotate in suitable bearings as 12 in the frame 13 of the machine. A rotary'motion is imparted to the shaft 11 by .a pulley not shown in the drawings, said rotary member being rotated in the direction of the arrow at (Fig. 3). V A receptacle 14 for wax is located beneath the work rubbing member 10 and said work rubbing member preferably projects down into said receptacle. The wax is kept at about the height of the dotted line b in said receptacle and is heated by a suitable burner 15 located beneath the receptacle '14. The

war: 16 in a melted condition is fed from shaft 19. I

The rock-shaft 19is adapted to rock in a bearing 20 formed in the waX receptacle 14 and said rock-shaft has fastened to its outer end. an arm 21 which is slotted at 22 to receive a stud 23 said stud being clamped to the arm 21 by a clamp nut. 24. A link 25 is pivoted upon the stud 23 atone end thereof andis connected by a pin 26 at its other end to a rocker arm 27. j Said rocker arm has rotatably mounted thereon cam roll -28 which: is arranged to. bear against the pe- "riphery' ofthe cam 29fastened. to a shaft 30. The shaft 30 is j'ournaled to rotate in' bearings 31 on the frame of the machine and has fastened thereto; a ratchet 32 at the opposite end, thereof from that to which the cam '29.,is fastened.

The ratchet 32 is heldi'n position against 1 aecidental rotation bya roll 33 which bears against the periphery of said ratchet and is 'nioimt'ed upon vertical pin 34 adapted to slide in' a' recess 35 in the wax receptacle, said roll being pressed against the periphery of said ratchet .by aspring 36which is inclosed within the recess 35 and bears against the lower end ofthe pin 34'.

An intermittent rotary motion is imparted tothe shaft 30 by a pawl 37 which is pivoted on a pin 38 fast to the pawl carrier 39 which is mounted to rock upon the cam shaft 30 and has a rocking movement imparted thereto by an eccentric rod 40 which is connected to 'an eccentric strap-41, said eccentric strap encircling an eccentric 42 formed upon one member of a clutch 71.

Said member-70 is loose upon the driving shaft lland has a conical face '72 thereon adapted to be engaged by a similar 'conica'l' face 73 formed upon the other member 74 of said clutch 71. The member 74' is fastened by a set-screw to thehub 76 of the rotary work rubbing member 10. Said rotary work rubbing member is loosely mounted upon the shaft 11 so that the same may be rotated to a limited extent independently of said shaft and moved longitudinally upon said shaft. It will thus be seen that the rotary work rubbin member andthe member 74 of the clutch%l are, in effect, a single piece and move as one piece. A pin 77 fast to theshaft 11 projects into an inclined slot 78 formed in the hub 76 ofthe rotary member 10. The parts70 and 74 of said clutch are normally held apartthat is, with their faces 72 and 73. out of frictional contact with each other,- by a pin 79 \vhichslides in the recess extending longitudinally within the member 70. said pin being held with its outer end in frictional engagement with the adjacent end of the member 74 by aspring 81. I

The pawl 37 is held in engagement with the teeth of the ratchet 32 by a spring 43 and is thrown out of engagement with saidteeth by a tripper consistin of a pin 45 fast to an arm 46 on a lever 4 v The lever 47 is pivoted upon the shaft 30 and is locked in position? by a spring-actuated'locking pin 48 which is heldby a spring 49 in engagement with any one of the teeth 50 upon the lower end of an arm 51 on the lever 47. The lever 47 is set indifferent positions by hand and is locked in the position in which it is set by the spring pin 48. As said lever is moved in one direction or the other the pin 45 will be engaged sooner or later, respectively, by an incline 52 on the tailpiece 53 of the pawl 37. Evidently as the lever 47 is;moved=to set the'pin 45 upwardly (Fig. 3) the incline 52 onthe tailpiecei53- will engage said pin 45 sooner'than whenv saidpin: is set downwardly from the position shown in "Fig. 3 and thus the pawl will be thrown out ofengagement with the r ratchet 82 at different times, according to the location of the pin 45, and will also be allowed to drop into engagement with said teeth at different times according to the position of said pin. Consequently, the feed of the ratchet 32, or the distance to which it is moved at each rotation of the shaft 11, will be increased or diminished according to the position in which the tripper pin 45 is set. Thus the number of times that the spring fingers 17 are brought into and out of contact with the periphery of the work rubbing member as compared with a given length of time during which the heel of the shoe is held in contact with said work rubbing member may be increased or diminished according to the position in which the tripper pin 15 is set by means of the lever 47.

The general operation of the mechanism hereinbefore specifically described and illustrated in Figs. 1, 2, 3 and 8 is as follows: Assuming the wax in the wax receptacle 1 1 to be melted by means of a flame from the burner 15 and the shaft 11 to be rotated in the direction of the arrow a, the operator places the edge of the heel of a shoe against the Periphery of the work rubbing member 10 and as he does so he applies a frictional resistance to the free rotation of said work rubbing member which results in the pin 7 7 moving forwardly in the slot 7 8 and, as'

said slot is inclined this action will cause the member 74 of the clutch 71 to be forced toward the member of said clutch until the surfaces 73 and 72 are pressed into frictional contact with each other, the pin 79 being pushed backwardly against the resistance of the spring 81. The parts 74 and 70 of the clutch thus being clutched together will rotate the eccentric 4:2 and thus, through the eccentric strap 41 and eccentric rod 40, a

rocking motion will be imparted to the pawl carrier arm, thus causing the pawl 37 to rotate the ratchet 82 to a greater or less extent according to the position of the tripper pin.4c5, as hereinbefore described. As said ratchet is rotated the shaft 30 will be rotated and the cam 29 will be rotated in the direction of the arrow at, thus moving the rocker arm 27 and through the link 25 rocking the arm 21 and the rock-shaft 19 so as to move the fingers 17 alternately from the position shown in full lines to that shown in dotted lines (Fig. 3). This action will intermittently carry wax by means of the fingers 17 into contact with the periphery of the work rubbing member 10 and the amount of wax delivered may be increased by moving the lever 17 toward the right (Fig. 3) and decreased by moving the same toward the left (Fig. 3), the pawl in the former case being allowed to drop into the teeth of the ratchet sooner than in the latter case.

As soon as the heel has been sufliciently wax treated and burnished, the operator removes the edge of the heel from contact with the periphery of the work rubbing member 10 and as soon as he does so the part 74 will be moved away from the part 70 by the spring 81 and spring pin 79, thus disengaging the two parts of the clutch and allowing the shaft 11 to rotate while the member 70 of the clutch remains stationary and the wax feeding means is thus thrown out of action so that no more wax will be fed to the periphery of the work rubbing member 10 until the operation hereinbefore described is repeated.

While we have described our invention and illustrated the same as particularly adapted to be used in that form of machine in which wax is contained in a wax pot and from said wax pot conveyed to the periphery of a work rubbing member by certain specific mechanism, we do not wish to be understood as limiting our invention to this particular embodiment thereof, as the Waxmay be conveyed to the work rubbing member in a variety of ways and by different mechanisms without departing from the spirit of our invention, particularly that portion of our invention which consists in throwing the wax supplying mechanism into operation by pressing against the periphery of the work rubbing member or by offering resistance to the free rotation of said work rubbing member, howsoever that resistance may be applied.

By making the fingers 17 of spring wire, it is evident that the same will conform to the convex cross-sectional contour of the periphery of the work rubbing member 10, so that said fingers will automatically adapt themselves to the shape of said periphery and the wax will be applied in strips extending around the periphery of said work rubbing member. The amount of wax which is applied to the periphery of the work rubbing member, as hereinbefore described, may be increased by increasing the number of times that the fingers 17 are brought into contact with the periphery of the work rubbing member 10, per minute.

Referring to Figs. 4 and 5: In Figs. 4 and 5 a modified form of wax feeding memher is illustrated in which the fingers 54, which feed the wax to the work rubbing member, do not necessarily yield in themselves, but are fastened to holders 55, all of which holders are pivotally mounted upon a rod 56 which is fastened at its opposite ends to ears 57 forming a part of a carrier 58 which is fastened to a rock-shaft 59, said shaft being adapted to fit in the bearing 20 and to be rocked by the arm 21 similarly to the rock-shaft 19 in the form of our invention embodied in Figs. 1, 2, 3 and 8. Each of the holders 55 is provided periphery of said work rubbing member.

Thus said fingers will yield, although not necessarily themselves made of spring metal.

In Figs. 6 and 7 another modified form of wax feeding member is illustrated in which 61 are the fingers and 62 are the holders to which said fingers are fastened,

said fingers beingsupported upon a rod 63 extending therethrough, and the holders 62 being adjustably fastened to said rod by meansof screws 64:. The rod 63 is clamped to cars 65 upon the carrier 66 by a clamp nut 67. The carrier 66 is fastened to a rockshaft 69 which is adapted to rock in the bearing 20. It will be seen that by adjusting the different holders 62 to the proper position and fastening them to the rod 68 by the set-screws 64 and then tightening the rod 63 in the ears 62, by means of the clampnut 67, the fingers 60 may be arranged in series in a curve adapted to conform to the curve forming a cross-sectional contour gf the periphery of the work rubbing mem- Having thus described our invention, what we claim and desire by Letters Patent to secure is:
